Linux Fieldbus Coupler
4.5.2 FTP Server (ftpd)
FTP can be used to exchange files between a PC and the Linux fieldbus
coupler. Linux need not necessarily be installed on the PC since Windows also
provides FTP client functions.
Other network participants can also login via FTP (condition upon delivery).
Just like for the telnet support, a corresponding entry is in the inetd.conf file.
The ftpd daemon is started via Ethernet if requested .
FTP File Exchange between PC and Fieldbus Coupler via Ethernet
An FTP client is required in order to exchange FTP files between a PC and the
Linux fieldbus coupler via Ethernet. The Windows Explorer also offers the
possibility to do that, however, we do not recommend this approach since the
Explorer has many disadvantages (very slow communication, wrong
interpretation of the directory structure, view is not updated which confuses
the user). To use the Explorer, the following entry is made in the data record:
ftp://username:password@hostname.
Example: ftp://user:user@192.168.1.12.
The user administration is analogous to the Linux console password and user
administration and is described in chapter 4"Board Support Package".
To use FTP, run the FTP program via the DOS console when using the
Windows operating system or via the Linux console when using Linux. To do
so, enter ftp <hostname/IP> in the console and answer the questions about user
and password (see following figure):
